Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Aider

  • Requires comfort working in a terminal rather than a graphical IDE
  • Has no hosted or managed version, so users must supply and pay for their own LLM API access separately
  • Depends heavily on the chosen underlying model's quality, so results vary by which LLM is configured
  • Lacks a built-in autonomous multi-step task runner comparable to agent-style products

SST

  • Primarily optimized for AWS with Cloudflare support
  • Learning curve for developers unfamiliar with infrastructure concepts
  • Limited documentation for some advanced use cases
